JOHN H. DALE, OF NEW YORK, N. Y.

SHADE-HOLDER.

To all whom it may concern:

Be it known that I, JOHN H. DALE, a citizen of the United States,residing. at the city of New York, in the borough of Manhattan and Stateof New York, have in vented certain new and useful Improvements inShade-Holders, of which the following is a full, clear, and exactdescription.

My invention relates to a form of shade holder or support particularlyfor use with electric fixtures. The ordinary holder for this purposemakes use of a sheet metal frame with clamping screws which have to betightened upon the shade at a number of points thereabout. Thismanipulation is troublesome, and furthermore objectionable as the natureof the support is absolutely unyielding to accommodate any expansion andcontraction of the shade.

It is one purpose of my invention to provide a shade holder which claspsinto firm engagement with the shade by a single movement or operation,but which holds with great security in use. I also provide a fasteningwhich accommodates any expansion or contraction which may take place inthe material of the shade. I further provide for the convenientattachment of the shade holder to the usual lamp socket of the typeordinarily employed and either screwed to a wall bracket or dependingfrom a flexible cord connection. Lamp sockets of this class ordinarilyhave a circumferential groove in which a part of the holder is engagedby a clamping screw. This is obviously expensive and troublesome. I makeuse of a spring means for this purpose, in combination with the springclasp which holds the shade. In one form of the present invention I makeuse of the same springs for holding the shade and engaging the socket.

\Vith these various and other objects in view, my invention consists inthe features of construction and combination as hereinafter set forthand claimed.

In the drawings: Figure 1 is a side view of a shade holder embodying theprinciples of my invention in use with an ordinary switch socket andshade. Fig. 9. is a vertical sectional view of the same. Fig. 3 is a bottom plan view of the holder. Fig. 4 is a vertical sectional view of aslightly modified form of the invention.

Referring'to the drawings, in which like parts are designated by thesame reference Specification of Letters Patent.

Application filed July 3, 1908.

Serial No. Ml/74:2.

sign, 1 indicates a shade holder conveniently made of sheet metal, spuninto a somewhat conical or flaring outline as shown in Fig. 2, and openat its ends 2 and 3 to receive the lamp socket and the shaderespectively. The form of the shade holder may be of any ornamentalcharacter desired, but I prefer that shown, having a central zone a withperforations for the escape of hot air, and having beads forminginternal annular grooves 5 and 6 at the portions immediately adjacent tothe respective openings 2 and 3. S designates a ledge which may beformed in a plane transverse to the axis of the device. This ledge formsa stiff support for the springs which I employ for holding the shade,and in some instances, the lamp socket as well.

In Figs. 2 and 3 I have illustrated three spring blades 9 fastened tothe ledge 8 at equally spaced-apart points on its interior under face inany convenient way, as by means of screws or rivets 10. These springsdepend downward in a form or outline generally corresponding to that ofthe holder, but out of contact with its interior surface, so as topermit an outward yielding movement. At their lower ends, these springsare rounded inward to provide protuberances 11 adapted to engage theusual groove or rim at the top of an ordinary shade. The protuberances11 are so formed on the springs that they lie opposite the groove 6 ofthe holder, into which they are capable of yielding outwardly when thedevice is being at taehed to the shade.

In the form of the invention shown in Figs. 1, 2, and 3 the springblades 9 are continued upward as well as downward from their supportingrivets 10, forming prongs 12 with inwardly directed protruding portionsor projections 13. The form of the upward extensions or prongs 12 ismost conveniently made a reverse curve at their extremitiescorresponding roughly to the out line of the head 5 situated immediatelyoutside the same and adapted to cooperate with the usual bead l-ilof theswitch socket. These prongs are normally separated a slight distancefrom the surrounding wall of the holder so as to be capable of yieldingoutwardl y when engaging the lamp socket.

The use and operation of the holder will be clear from the foregoingdescription. It is merely necessary to snap the prongs 12 over the usualhead of the socket and sumlarly engage the prongs 11 over a shade of theordinary character, whereupon the parts are all firmly assembledtogether for use. The character of the engagement is sufficiently securefor all purposes and permits relative expansion and contraction of theparts. At the same time. the parts may be quickly disengaged andseparated whenever desired.

In Fig. 4 I have illustrated a slightly modified form of the inventionin which the spring blades 9 extend only downward from their supportingrivets, separate spring means being provided for engaging the switchsocket. A convenient spring means for this purpose is that which I havefully set forth iii my Patent No. 803,883, issued Nov. 7 1905, andincluding a spiral spring 15 which surrounds a metallic ring 16 withinthe upper groove 5 of the shade holder. This device is capable ofestablishing a firm connection with the usual bead of the socket whenpressed thereon, in an obvious way.

lVhat I claim is:

1. A shade holder comprising a sheet metal casing having a continuousunbroken lower edge and having a plurality of spring blades dependingtherein and adapted to engage a shade, said blades being concealed andlimited in their outward movement by said casing.

2. A shade holder comprising a casing having a bead at its lower sideand a plurality of spring blades Within said casing having bent portionswithin said bead adapted to engage a shade, whereby said spring bladesare yieldable outwardly with their bent portions entering said bead.

3. A shade holder having spring blades fastened at points intermediatetheir length within the shade holder, said springs having inwardlydirected protuberances at their upper and lower extremities to engage alamp socket and shade respectively.

In witness whereof, I subscribe my signature, in the presence of twowitnesses.
